Together with his colleague Bastian Obermayer (with whom he is not related) Frederik Obermaier initiated and coordinated the "Panama Papers"-revelations after an anonymous source provided 2,6 terabytes of internal data from the dubious Panamanian lawfirm Mossack Fonseca to them. Obermaier
co-authored an international bestseller about the project.

"The biggest leak in the history of data journalism" (Edward Snowden)

"With precision and purpose, The Panama Papers is what „Follow the Money” means." (Bob Woodward)

"... a tale of fearless and careful reporting... How to follow the money - the lesson of the Watergate investigation a generation ago - has been given a reboot for the age of
globalisation." (Financial Times)

Before the Panama Papers, Obermaier was part already of the international team of journalists, who revealed the "Offshore-Leaks", "Luxemburg-Leaks" and "Swiss-Leaks". After the Panama Papers, he and his colleague Bastian Obermayer also received the "Paradise Papers"-documents, which were published in
November 2017.

"The Paradise Papers make clear that we need, in the United States and throughout the world, a tax system which is fair, progressive and transparent." (Bernie Sanders)

"Absolutely breathtaking and so important." (Joseph Stiglitz, former Worldbank-chief-economist)

"What the Paradise Papers show is how dishonesty is being promoted on a mass scale and how corruption is being institutionalized." (David Cay Johnston, Pulitzer
prize-winning Trump-biographer)

For the Panama-Papers-revelations he was together with Bastian Obermayer and Vanessa Wormer elected Germany's "journalist of the year 2016". As part of the Panama-Papers-team he won the Pulitzer
Prize 2017 in the category "Explanatory Reporting".
